Objective    To compare the blood lipid levels in Uygur and Han patients with type 2 diabetes mellitus (DM) accompanying coronary heart disease (Yecheng County

Xinjiang Autonomous Region

China) and their clinical significance.     Methods    Blood lipid levels in 348 patients with type 2 DM accompanying coronary heart disease admitted  to No.18 Hospital of PLA from January 2009 to December 2010 were retrospectively analyzed.     Results    The triglyceride (TG) and total cholesterol (TC) levels were higher in patients with type 2 DM accompanying coronary heart disease than in those not accompanying coronary heart disease. The TG and TC levels were higher in Uygur and Han patients with type 2 DM than in those not accompanying coronary heart disease (TG: 2.87±0.52 vs 2.03±0.43 and TC:5.74±0.63 vs 4.91±0.54 in Uygur; TG: 2.11±0.34 vs 1.82±0.36 and TC: 5.52±0.43 vs 4.62±0.45 In Han

P0.05).The incidence of hypercholesterolemia was higher in Uygur patients than in Han patients (12.96% vs 7.19% in male patients and 13.89% vs 6.72% in female patients

P0.05).     Conclusion    High TG and TC level is the important risk factor for type 2 DM accompanying coronary heart disease. Controlling blood sugar and lipid level can reduce the incidence of diabetic arteriosclerosis. The blood lipid levels and lipid metabolic disorder types are different in different nationalities.
